Sigils were pretty much brushed under the rug with the upcoming update. They’re still there but they play a smaller, supportive role.

Changes include:

No longer on its own section on the main HUD. Now appear around the fear-o-meter.

Size of them are smaller, take up less room. Can’t hide inside of them.

Can teleport between uncorrupted ones by pressing use on them.

Corruption doesn’t unlock anything or end the game. Only adds a flat zombie resistance, I think all 3 would be 15%. This may be changed to a multiplier, so like having all 3 corrupt would multiply fear by 1.25 and none corrupt multiply by 1.00.
